A TTORNEKS United States Patent 3,048,368 PULLING DEVICE Linferd G. Linabery, Sr., Gladwin, Mich. Filed Oct. 1, 1958, Ser. No. 764,551 2 Claims. (Cl. 254130) This invention relates to post or stake pullers of the type used to pull posts, stakes, signposts, and marker posts which are solidly imbedded in the ground.

One of the prime objects of the invention is to design a stake puller of simple, practical, rugged, and inexpensive construction, which is readily operable by one man, and which can be used for pulling all types of highway posts, signposts, and/or stakes anchored in the ground to support signs, form guard rails and barriers and/or posts for anchoring cables, etc.

Another object of the invention is to design a relatively compact puller, expressly designed to pull posts or pipes on which street signs, markers, and other objects are mounted, which requires no skilled labor to apply and manipulate, and which is easily transportable from one location to another.

A further object is to provide a puller device which can be easily spotted in position, and which is readily adjustable to the purpose for which it is designed.

Still a further object is to provide a pulling attachment equipped with adjustable removable handle means for regulating the leverage, and providing a device which can be readily transported and stored.

A further object still is to provide compact readily operable reinforced jaw members which will withstand the heavy stresses and strains created by the puller without breakage or bending and which are easy to place in position on the post.

With the above, and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion, and minor details of the construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawings:

FIG. 1 is a side elevational view of my improved pulling device showing it in engagement with a post to be pulled.

FIG. 2 is a front elevational view thereof, the post and gripping jaws being omitted.

FIG. 3 is an enlarged elevational view of the gripping jaws showing them in engagement with a post.

FIG. 4 is a plan of the gripping jaws, the chain and post omitted.

FIG. 5 is a part sectional plan view taken on the line 5-5 of FIG. 1.

'FIG. 6 is an enlarged perspective inverted plan view showing the individual gripping jaws and the chain connection.

FIG. 7 is side elevational view of the handle.

Referring now more specifically to the drawings in which I have shown the preferred embodiment of my invention. The numeral 10 indicates a pair of spacedapart, elongated base members connected by means of a transversely disposed angle 11 and a fiat plate member 12, the ends of these members 11 and 12 being welded to the base members 10 in the usual manner, and a centrally disposed plate 13 is welded to the inner edges of the members 10, thus providing additional bearing surface for the puller.

A vertically disposed post P is disposed between the members 11 and 12 and comprises identically similar Patented Aug. 7, 1962 angles 14 secured in position by welding or in any other desired manner. Angularly disposed braces 15 extend from the ends of the members 10' to the individual angle members 14 at a point intermediate their length to brace and reinforce the structure, and a transversely disposed rod 16 spans the brace members 15 for further bracing and providing a hand hold for handling and positioning when desired. One or more cross ties or plates (not shown) can be welded to the members 14 which form the post to brace and provide additional rigidity to the structure.

A bolt or pin 17 spans the post members 14 at a point directly adjacent the upper free end thereof, and a handle member H is mounted thereon, the one end section of said handle being preferably in the form of a flat section 18, the lower face of which is formed with a plurality of teeth or notches 19 to accommodate the pin 17.

A pipe 20 forms an extension of the plate 18, the end being flatted as at 21 and is welded to the plate 18, said handle 20 being hollow to accommodate another pipe section 22 (see FIGS. 1 and 7), to provide all necessary leverage. A pair of links 23 are pivotally connected to the flatted end of the bar 18 by means of a bolt 24, and a hook 25 is connected to the links as at 26 and for a purpose to be presently described.

The handle H is preferably bent as at 27 so that the outer end section of the handle is upwardly inclined as shown in FIGURESl and 7 of the drawings. A brace 28 is welded to the handle to span the bend 27, and it will be obvious that the handle may be adjusted on the pin 17 to provide additional leverage when desired.

The design of the post and stake gripping members is of' the utmost importance as these members are subjected to very severe strains and stresses, when pulling deep securely anchored posts because the harder the upward pull, the more firmly the members engage or grip the- 3232, and openings 32' are provided in said walls with pins 33 welded in said openings, the projecting ends of said pins being formed with a head 34 and for a purpose to be presently described.

Angularly disposed parallel braces 35 are spaced from the side walls 32-32 a distance sufiicient to accommodate the side walls 38 of the jaw G therebetween, by means of blocks 36, the one end of each brace being welded to the bar handle 29, the opposite free end having a suitable opening (not shown) which accommodates the pins 33, thus preventing bending of the pins and reinforcing the entire structure.

'The opposite gripping member G is formed exactly the same, excepting that it has no pins or pin reinforcing means, the jaw G being of a width sufiicient to receive the walls 3838 of the jaw G therebetween; and inclined, slotted passages 39 are provided in the lower edges of the members 38 to accommodate the pin-s 33 when the jaw members are assembled in interlocking relation around the post or stake F. The upper inner edge of both jaws have a rib or bead 40 of hard metal to minimize wear, etc.

A suitable opening is provided in the free end of each bar handle section 29 and one end of a flexible chain C is attached thereto as shown, and when the jaws are placed in position on the post or stake F, with the pins 33 3 seated in the passages 39, the chain C forms a yoke which is attached to the hook 25.

To pull a post, the workman first places the jaws in post engaging position and thenforces the handle H downwardly, causing the gripping jaws G and G to pivot about the pins 33 so that the upper hardened edges 40 firmly grip the stake, after which the handle is actuated to raise the post from the ground, and should the stake or post be buried in the ground to a considerable depth, a second pull may be necessary to raise same.

To facilitate carrying the puller from one location to another, I provide a transverse rod R which I weld to the post, as shown, the ends projecting a distance sulficient to form a good hand hold.

The links 23 can be of any desired length, and the post sections 14 can be spaced as desired, either by a fiats eparator (not shown) or a brace can be added if necessary. The device can be easily carried or moved overrough terrain where road signs, stakes, or posts may be placed by utilizing the rod R, and the base members and 13 provide ample bearing.

Leverage is controlled by shifting into a selected notch 19 to shorten or increase the distance between the load and the fulcrum point 17, and the handle is, of course, extensible as previously described.

From the foregoing description, it must be obvious that-I have perfected a very simple, practical, rugged and inexpensive stake puller for pulling street and highway signs, highway guard posts and barriers, and/or stakes of a similar nature which are buried in the ground.
